A “C” or series of “C” or other characters or characters are displayed on the vision display screen. Using an input means such as a touch screen monitor or an operation bar, the user indicates the direction of the displayed characters, or identifies them by matching them with enlarged characters having the same design and direction. These characters are displayed for a specific time and can be replaced arbitrarily.

(Example 2. System used as a screening device)
This system can be used as a screening device for visual acuity by displaying a character of a specific size that is used for screening of the desired visual acuity level. For example, the system displays 5 “C” columns randomly shown, or an array of 9 C, for intermediate and near vision. The size of C is set for one visual acuity such as 20/20, 20/30, etc. All four directions that C is facing are randomly displayed on the first four displays. If there is nothing or one that the user can't see, the user passes. If there are two things that the user cannot see, the user is rejected. If one of the four displayed C arrays is not visible, the fifth C or C array should be facing the same direction as it was not visible. Examples of C sequences are as follows:

この手順は、片方の目を手で覆った、または閉じた状態で一つずつ（単眼視力評価）、あるいは両方の目を開けた状態で（両眼視力評価）、ユーザのそれぞれの目を評価する。

This procedure evaluates each eye of the user with one eye covered or closed (single-eye vision evaluation), or with both eyes open (binocular vision evaluation). To do.

(Example 3. System used as a visual acuity measurement device)
This system can be used as a visual acuity measuring device by identifying the smallest character from character groups of various sizes that the user can see at a given viewing distance. For example, the system displays a series of characters of different sizes. Each size is shown repeatedly. If the user correctly identifies all or almost all characters or their orientation, the next smaller size is displayed, and this process identifies the wrong number of characters or their orientation until the evaluation is completed or until the user finishes the evaluation. Repeat until. If the user correctly identifies the smallest displayed character, the user's visual acuity is above this visual acuity level. If the user incorrectly identifies a predetermined number of characters at a predetermined visual acuity level, the user's visual acuity is the next highest visual acuity level.

(Example 4. Computer vision evaluation)
All measurements are made with complete vision correction, such as glasses or contacts. The system allows the user to (1) enter the user's normal viewing distance (inches, feet, centimeters, etc.) into the computer monitor when using the computer or display screen, or (2) with respect to the system monitor screen Instruct to move to a position approximate to the distance when viewing the computer monitor. When the user suggests that the user is at normal viewing distance, the distance sensor in the system records the viewing distance.

(Example 5. System used as a screening device)
Using the viewing distance found from the above procedure, the system screens computer vision by displaying characters of a specific size that are used to screen for the desired vision level, such as 20/20, 20/30, etc. Can be used as a device. The procedure for visual screening evaluation follows that described above.

(Example 6. System used as a visual acuity measuring device)
This system can be used as a computer vision measurement device by identifying the smallest character from a group of characters of various sizes that a user can see. Using the viewing distance found from the above procedure, the size of the displayed character can be varied to correspond to a specific visual acuity level at a known viewing distance. The user's visual acuity is obtained by identifying the smallest character from various sized character groups that the user can see on the vision display or monitor screen. The procedure for visual acuity assessment follows that described above.

(Example 7. Clear vision)
A user wearing a multifocal lens such as a bifocal, trifocal, or progressive lens often has difficulty viewing the entire computer monitor screen. They usually compensate for this by moving their heads and making them visible through another part of the multifocal lens. This can hurt the neck and upper back, reducing productivity by moving the neck excessively. The purpose of clear field of view evaluation is to secure a portion of the computer screen that can be easily viewed by the user without moving his head for multiple lens users. This evaluation also checks the segment height of the multifocal lens to ensure that it is properly adjusted.

In the following, an example of the procedure and narration is described, but it is not necessarily the only procedure and explanation that expresses the evaluation of the clear field of view.
The system prompts the user (1) the user's normal viewing distance (inches, feet, centimeters, etc.) when using the computer to the computer monitor, or (2) the computer monitor relative to the system monitor screen. To move to a position that approximates the distance when viewing When the user suggests that the user is at normal viewing distance, the distance sensor in the system records the viewing distance. The test is performed with a single eye with the user covering or closing one eye. Both eyes are tested in this way.
Narration example:
The text will now appear on your computer monitor and you will see a black dot in the center. Always look at this black dot. Please hide one eye. However, do not close this eye. Look at the black dot with your eyes. From now on, the line across the text will slowly move upward. Let me know when this moving line reaches the point where the text begins to fade. At that time, press the button attached to the tip of the control rod.
After that, the line moves down, right and left. When this line reaches the part where the text begins to fade each time the line moves, press the button at the end to let it know. For accuracy, you should always be looking at the black dots, not the moving lines. Press the button at the tip to start or resume the test.

  The (analysis) system calculates the clear field of view as an area where the user can clearly see without moving his head, and as an area within the boundary of the upper, lower, left and right lines drawn by the user. The calculation result is expressed as a percentage by dividing the clear visual field area by the total area of the monitor screen. This analysis compensates for differences in the user's monitor size. A high percentage result indicates that the user is working on the computer without moving his head too much to see the monitor screen. A lower percentage result suggests that you probably need to move your head too much to see all parts of the monitor screen clearly. The system may encourage the user to get a new multifocal lens prescription so that a larger part of the monitor can be seen, or to get special glasses made specifically for the computer.

  The two areas of the clear field of view (one for each eye) may not be aligned vertically. This may suggest that the segment height of the user's multifocal lens is not properly adjusted. This can also occur when the lens has optical aberrations. This can cause eyestrain, headache, and blurred vision when working near or intermediate distances, such as looking at a computer monitor screen. The system may encourage the user to undergo a specialized eye examination and have the lens segment height mismatch corrected.

(Example 8. Central vision evaluation)
All measurements are made with complete vision correction, such as glasses or contacts. Central vision assessment is related to the internal health of the eye, especially the health of the retina. The assessment is useful, for example, in determining the user's ability to view the entire displayed image, and the displayed image without distortion, appearing on a computer monitor screen.

  This evaluation is performed using a grid line running vertically and horizontally and a point at the center. This method can be used with white lines on a black background, black lines on a white background, or certain colors that produce reasonable contrast between the line and the background. The system asks the user to be located relatively close to the monitor screen. This distance varies depending on the size of the monitor screen used. A distance sensor adjusts an LED or other physical means, such as a position adjustment bar, to inform the user that the user is at the correct viewing distance. The system asks the user to concentrate on the point at the center of the grid during the evaluation. This evaluation is performed with a single eye.

(Example 9. System used as a screening device)
A question is asked about what the user is looking at. The questions include, but are not limited to:
• Can you see a point in the center of the grid? • Can you see all the corners and sides of the grid? • Are there any lines that become invisible, distorted, or wavy when looking at the center point? If the answer to any of the above questions is yes, it indicates that there is a problem with the user's central vision and the system will ask the person to have an eye care professional check the eye. I will advise you to take it.

(Example 10. System used as a measuring device)
This system is used as a measuring device by asking the user the above question and showing the part that the user cannot see or clearly see in the grid if the user's answer to either is yes be able to. This can be accomplished by a touch screen or other input device that allows the user to accurately indicate certain parts of the grid that are difficult to see clearly.

  Central vision evaluation can be made more sensitive to each individual by changing the brightness of the grid lines relative to the background, whether used as screening or as a measuring device. A way to achieve this is to ask the user to reduce the brightness of the grid lines until the grid lines are no longer visible. The user then increases the brightness of the grid lines until the grid lines are finally perceptible. The user then begins the above evaluation.

(Example 11. Comparative visual acuity evaluation)
All measurements are made with complete vision correction, such as glasses or contacts. A person's visual acuity using a high-contrast eye chart does not suggest or predict how well the person will look in low-light conditions. Contrasting visual acuity assessment helps determine a user's visual acuity level at various levels of reduced contrast between "C" or other letter numbers and the background in which they are displayed. In this evaluation, a series of characters with different contrast with the background is displayed, and the smallest character size visible to the user with a certain contrast is measured.

(Example 12. System used as a screening device)
The contrast visual acuity evaluation can be used by using the display character size used in any of the above screening evaluations with various degrees of contrast. The contrast ratio between the displayed character and the background can range from 100% contrast to 0% contrast, but due to practical limitations on the evaluation time, there is only a limited number of specific levels of contrast. Cannot be displayed. These are contrast ratios of 50%, 20%, 5%, or other combinations in the range of 100 to 0%.

  The user is required to identify the character or the direction of the character with a specific character contrast ratio by the method described in the visual acuity evaluation above. A pass / fail evaluation can be performed by setting a character size (corrected by a user viewing distance) and a contrast ratio threshold. The resulting scoring method is also similar to the visual acuity assessment described above.

(Example 13. System used as a measuring device)
Using any of the above visual acuity measurement methods, the system can display the character size (adjusted by the user's viewing distance) corresponding to the user's best visual acuity. Using this character size as a starting point, the system reduces the contrast ratio of the character to the background in the manner described above. If the user incorrectly identifies a certain number of characters or character orientations at a given contrast ratio, the system increases the size of the displayed characters to accommodate the new visual acuity level at this contrast ratio. This process is repeated until a test result is obtained based on the visual acuity level and contrast ratio displayed by the system.

  analysis. By following the above procedure, a chart of visual acuity and contrast ratio is determined. Usually, when the contrast ratio is low, it is expected that the character size that can be seen increases as the visual acuity level decreases at a predetermined distance. By plotting these results and comparing them to an age-corrected normal population, the system can identify users with low contrast vision below average. This suggests various ocular health problems, such as, but not limited to, Wagner's hereditary vitreous retinal degeneration, macular edema, diabetic retinopathy, cataract formation, and various eye surgery and treatment results There is a possibility. This result is also plotted over time to track various eye health problems as described above.

(Example 14. Perspective adjustment range)
The user's perspective adjustment range can be evaluated by moving them toward a visual target such as a chart or a computer monitor screen. By measuring the distance by the above means, it is possible to determine when the user first experiences “the first sign of haze” as he / she gradually approaches the object to be viewed. The first sign of haze is signaled by the user using keystrokes, a mouse, a control stick, voice, or other input device. Using this distance, the user's ability to adjust can be reached, and the age can be adjusted to determine a normal / abnormal adjustment pattern.

(Example 15. Adjustability)
The time it takes for the user to change the focus from a near image to a distant image so that the distant image is clearly visible can be defined as their “near to far” adjustment capability. The user's ability to adjust will show an increase in the time needed to focus on distant objects because the user is stressing the adjustment system with too close work, such as computer work . This same accommodation stress will increase the time it takes to change the focus from a distant object to a nearby object until the near image is clearly visible ("distant to close" adjustment ability).

  The adjustment ability can be evaluated by showing the user a short distance image, for example, an image displayed on the LCD used for the near vision evaluation for a specific time. The user is then prompted to notify by any of the above input devices when changing focus, and is also required to focus on a distant image, for example, an image displayed on an LCD used for distance vision evaluation. The user again informs the input device as soon as this distant image is clearly visible. This is the ability to adjust from near to far from the user. This process is repeated when going from a distant image to a near image to determine the ability to adjust from far to near. These evaluations are repeated many times to obtain an average.

(Example 16. Blink rate)
The blink rate can be an important factor in assessing the dry eye state of people who are engaged in near-point work and computer work for a long time. The blink rate of these people decreases dramatically and often causes dryness as the corneal surface is exposed to ambient ambient air and evaporates. Dry eye conditions often involve redness of the eyes, burning sensation, foreign body sensation, or tingling in the eyes, and blurred eyes. Therefore, the blink rate can be used as a tool for evaluating the presence and degree of dry eye or the risk of becoming dry eye.

  Method. A system that calculates the blink rate and measures the blink interval, known as the blink interval (IBI). This is done by recording the number of times the user blinks within a predetermined time and averaging the time interval between blinks during this period. The longest IBI is also important because it is a measure of the period during which dryness can occur and the potential risk of developing a dry eye condition.

  The second parameter, tear film disruption time (TFBUT), is obtained by asking the user not to blink (gaze) until the user complains of eye discomfort. The recording of the time from the last blink to the eye discomfort is an approximate value for TEBUT.

  analysis. The blink rate of the user's statistical sample correlates with the symptoms of dry eye, and the level of dry eye, such as mild, moderate, and severe, is associated with various thresholds of blink rate. Another way is to compare a person's TFBUT to the person's IBI. If TFBUT is shorter than IBI, it indicates a dry eye condition, and the magnitude of the difference between the two can be used to indicate the degree of condition such as mild, moderate, or severe.

  Using a camera and a light source (IR-infrared, etc.), the light reflected on the surface of the cornea can be used as an indicator of dry eye. In this dry eye evaluation method, changes in brightness and / or sharpness of an image reflected on the surface of the cornea are observed. Using these parameters and measurements of the area they occupy, it is possible to identify where the cornea is dry.

(Example 17. Blink reflection)
Knowing the user's blink rate creates various means for the user to blink and presents the possibility of measuring the effectiveness of such interventions. Various means for blinking a user are stimuli that are consciously or unconsciously sensed through one or more of the five senses. Examples of such stimuli include, but are not limited to, visual stimuli that cause a natural blink response, warning or notification of reduced blink rate status to the user, or visual, auditory, tactile, taste, and And / or other biofeedback reactions involving hearing.

  By tracking changes in blink rate associated with a given blink stimulus, you can evaluate the effectiveness of those stimuli, and you can modify specific stimuli to achieve greater blink rates. Or you can change to a new stimulus to achieve the desired result.

(Example 18. Evaluation of allergy and dry eye)
An assessment of eye allergy and dry eye can be made by having the user answer some appropriate questions. The answers to these and similar questions can be assigned numerical values or score calculations set to determine the severity of eye symptoms. Severity categories can be assigned mild, moderate, moderate, severe, or other terms that describe the user's symptoms. Advice is relevant to each category, such as recommended products or services, or having an eye exam taken by an eye care professional.

(Example 19. Use of this system in a corporate or industrial environment)
The system can be set up as follows.

（内容）ステップ１：コンピュータ労働者、工場労働者、その他の会社員は、視覚評価を完了したら名前とメールアドレスを入力する。ステップ２：この情報はデータベースへ送信され、ユーザのファイルが作成される。ステップ３：既往症、労働形態、使用機器、環境条件、そして視覚および／または筋骨格疾患などのトピックをカバーした人間工学的調査に労働者が答え、データベースへメールする。予めプログラムされたアルゴリズムを使った解析が、視覚データと人間工学的調査から行われ、人間工学／人事／安全担当スタッフ、および／またはユーザへメールされる。定期的な視覚評価と人間工学的調査によって、労働者の健康、快適感、業績を継続的に最適化することができる。

(Content) Step 1: Computer workers, factory workers, and other office workers enter their names and e-mail addresses after completing the visual evaluation. Step 2: This information is sent to the database and a user file is created. Step 3: Workers answer an ergonomic survey covering topics such as pre-existing conditions, work styles, equipment used, environmental conditions, and visual and / or musculoskeletal disorders, and mail to the database. Analysis using pre-programmed algorithms is performed from visual data and ergonomic research and emailed to ergonomics / HR / safety staff and / or users. Regular visual assessment and ergonomic research can continuously optimize worker health, comfort and performance.

(Example 20. Using remote, near, and other visual acuity assessments to accommodate users of various heights)
To allow a user looking at the system to perform distance vision, near vision, or other visual assessment, the user is displayed directly on the LCD, etc., or using one or more mirrors. You need to see the image. Such a system is provided to accommodate users of various heights.

  Thus, the kiosk in one embodiment provides a beam from a distance sensor (such as an infrared distance sensor) that is projected onto an adjustable mirror located in front of the user. As the adjustable mirror moves to the vertical position, the infrared beam begins to sweep downward. When a signal is issued to signal an object such as a user, the position of the adjustable mirror is recorded through a feedback loop of a servomechanism that drives the movement of the mirror. This initial signal detection is expressed as an angle and if the object standing in front of the system is a person, it estimates the user's top of the head. By knowing the distance to the user and the approximate position of the top of the head, the adjustable mirror is moved further down by a fixed amount so that the user can (1) display or other view above the adjustable mirror An object, or (2) a second mirror placed on the adjustable mirror and following the optical path (which is also composed of mirrors), and an image displayed at the end of the optical path Mirrors can be placed where they can be seen.

  The infrared distance sensor and adjustable mirror / servo mechanism described above can be used to measure the user's height and eye position. This information can be used to activate another servomechanism that adjusts the viewing angle of an object to be viewed for visual acuity evaluation, such as but not limited to an object displayed on an LCD.

  In an alternative embodiment, the position of the user's eyes can be measured using a camera and software, and the viewing angle adjustment described above can be made for various heights.

  In yet another embodiment of the invention, the user inputs his approximate height and the system mechanically adjusts the viewing angle of the display or mirror to view the viewing angle evaluation image displayed by the user. To be able to.

  In yet another embodiment, the user can manually or mechanically / electrically set the display angle using buttons or knobs to allow the user to view the displayed viewing angle evaluation image.

(Example 21. Optical path)
Incorporating many mirrors into the optical path, shortening the mirror spacing, or increasing the mirror spacing with fewer mirrors, and displays that users and users see according to the system size constraints required A certain distance optical path to the object can be achieved. In general, the smaller the number of mirrors, the less the degradation of the displayed image, but in order to secure a specific viewing distance between the user and the object to be viewed, the optical path between each mirror needs to be longer. There is. As the number of mirrors increases, degradation of the displayed image increases, but the optical path between the mirrors can be shortened, so that the size and dimensions of the entire optical path can be reduced. In addition, an optical path from the user to the displayed object can be formed by configuring the optical path so as to reflect an image using a mirror many times.

In addition, the arrangement of the optical chamber (9) and the computer (17) is shown. In one embodiment, there is an adjustable mirror ("peep mirror") actuated by a servo in the peep window (20). A distance sensor, such as an infrared distance sensor, is placed on the mirror, reflects off the mirror and travels towards the user. When the distance sensor senses a signal, for example the presence of a person, knowing the distance to the user and the angle of the mirror, the servo adjusts the mirror so that the user is at the end of the optical path of any length An object displayed on a monitor display, such as letters and numbers, can be seen. Alternatively, in another embodiment, the desk version of the kiosk includes a single monitor screen (42) that displays images on different portions of the display screen. The image displayed on a part of the screen (42) is reflected through optical paths of various lengths, displayed on a viewing mirror, and used for distance vision evaluation. An image of another part of the screen (42) is reflected through different lengths of the optical path and displayed on a viewing mirror for use in near vision evaluation. In another embodiment, the movable monitor screen (42) is moved to a normal viewing distance by the user and an image is displayed on the monitor screen (42) for use in evaluating the user's computer vision. Alternatively, the monitor can be fixed and the user can approach or leave the monitor to approach the normal distance for viewing the computer. The resolution of the image displayed on the monitor (42) can be increased by a reduction lens assembly placed over the displayed image. Included in the reduction lens assembly is a single lens, multiple lenses, single or multiple lenses with mirrors, etc. that effectively reduce the size of the displayed image and clearly improve the resolution. FIG. 13A is a top view view of a display (29), such as an LCD display, showing various visual acuity patterns, eg, distant or near visual acuity patterns, in different areas of the display (29), mirrors next to the LCD display (29). (43) and for generating on the viewing window (20). FIG. 13B is a side view of the mirror (43) and LCD display (29) shown in FIG. 13A, and the displayed far vision pattern is projected downward onto the mirror (47), which optically images the far vision pattern. Illustrates the reflection into the chamber (9) (not shown), and the mirror (43) is disposed obliquely, preferably at an angle of about 45 degrees in the horizontal direction, on which the optical chamber (9 ) (Which is not shown) is reflected, and the distance vision pattern is displayed. The LCD display (29) may be arranged as shown in FIG. 13B or rotated 90 degrees as shown in FIG. 13C to save space. FIG. 13C is a side view illustrating the manner in which the displayed near vision pattern is projected downward onto the mirror (48) and reflected to the user. The angle or height of the mirror (48) can be adjusted so that users of various heights and distances from the mirror can see the reflected vision pattern. In FIG. 13C, the near vision pattern is displayed closest to the viewer, projected onto the lower mirror (48), and reflected back to the viewer. The far vision pattern is displayed on the LCD portion farther from the viewer, projected onto the lower mirror (47), and reflected from the mirror (47) to the far vision optical path. An enlarged view of the distance vision mirror and display is shown in FIG. 13D. An enlarged view of the near vision mirror and display is shown in FIG. 13E. FIG. 14A is a front view display of the near vision pattern (50) reflected from the upper display (29) to the mirror (48). The angle or height of the mirror (48) can be adjusted so that users of various heights and distances from the mirror can see the reflected vision pattern (50). This is the view that the user sees from the viewing window (20), which is covered with a piece of glass (49), such as tilted glass. A distance sensor (16) is shown above the viewing window (20). FIG. 14B shows the image path (51) of the near vision pattern (50) reflected by the mirror (48), and the servo mechanism (52) and connecting link (53) for adjusting the mirror (48) to various angles. It is a side view display. The mirror (48) is attached with a bottom hinge (54) (as shown) or a top hinge (not shown) or is not hinged and is moved vertically by a servo (52) Thus, both height and distance from the mirror (48) are adjusted for different users. Glass, plastic, or other transparent material (49) separates the user from the mirror (48) and is placed diagonally to reduce glare to the user. FIG. 15A is a front view display showing the reflection of the distance vision pattern reflected on the mirror (48) seen by the user. FIG. 15B is a side view showing how the mirror (43) reflects the distance vision pattern received through the optical path (56) to the mirror (48) and from the mirror (48) to the user (57). is there. FIG. 16 is a diagrammatic representation of a distance sensor beam from, for example, an infrared distance sensor (16). The beam is directed to the adjustable mirror (48) and reflected from the mirror (48) to the viewer (57). By changing the angle of the mirror (48), the direction of the distance sensor beam can be changed. For example, if the servo mechanism (52) and the connecting link (53) move the mirror (48) to a more horizontal position, the direction of the distance sensor beam takes a more upward path. As servo mechanism (52) and connecting link (53) move mirror (48) to a more vertical position, the direction of the distance sensor beam takes a more horizontal path. The distance sensor beam may be arranged obliquely (as shown) with respect to the adjustable mirror or may be arranged vertically (not shown). FIG. 17A is a diagrammatic representation of how the distance sensor (16) and adjustable mirror (48) determine the height of the viewer or user (57). The angle of the mirror (48) is initially in a substantially horizontal position so that the path of the distance sensor beam (58) is on the head of most users. Using small increments, the servo (52) begins to increase the angle of the mirror (48) relative to the horizontal, thereby sweeping and moving the distance sensor beam (58) downward. When the path of the distance sensor beam intersects the top of the user (57), the distance sensor records the distance measurement to the user and the servo (52) records its position that is directly proportional to the angle of the mirror (48). Utilizing inputs to these algorithms, the computer sends a signal to the servo (52), which further moves the mirror (48) so that the user sees various vision patterns reflected on the mirror (48). Can do. The position of the adjustable mirror prior to use reflects the infrared beam at a higher angle than most users of kiosks. When a person approaches or activates the navigation screen, the mirror sweeps the infrared sensor beam downward. When the beam detects the top of the user's head, it first receives a signal. When the signal is first detected, it recognizes the distance to the user and the angle of the mirror so that the user can see through the entire optical path of the mirror and see the displayed object on the other side of the optical path. Is adjusted downward. Of course, one or more additional distance sensors can be used, or the distance sensor is not used when the user enters his height information. FIG. 17B is a diagrammatic representation of how the distance sensor (16) and adjustable mirror (48) determine the height of the viewer or user (57).
